Ukungasebenzi kahle okuvamile
Amaphutha okusebenza, ukuvuza kwe-nitrogen, ukunakekelwa okungafanele nezinye izenzakalo zizodala ukuthi i-valve yokusebenza ye-breaker iguge, ukuqhuma kwepayipi, ukushisisa ngokweqile kwendawo kawoyela we-hydraulic nokunye ukwehluleka. Isizathu siwukuthi ukucushwa kobuchwepheshe akunangqondo, futhi ukuphathwa kwendawo akufanelekile.
Ingcindezi yokusebenza ye-breaker ngokuvamile i-20MPa futhi izinga lokugeleza lingaba ngu-170L/min, kuyilapho ingcindezi yesistimu ye-excavator ngokuvamile i-30MPa futhi izinga lokugeleza kwepompo eyinhloko eyodwa ngu-250L/min. Ngakho-ke, i-valve yokuchichima idinga ukwenza umsebenzi onzima wokuphambukisa nokuthulula. Uma i-valve yokukhulula ilimele kodwa ingatholakali kalula, i-breaker izosebenza ngaphansi kwengcindezi ephezulu kakhulu. Okokuqala, ipayipi liyaqhuma, uwoyela we-hydraulic ushiselwa ngokwedlulele, bese kuthi ivalvu ehlehlayo iguge kakhulu nezinye izingxenye zeqembu lama-valve asebenzayo ommbiwa. I-hydraulic circuit elawulwa yi-spool (i-spool elandelayo ekhonjwe yi-oil circuit enkulu endaweni engathathi hlangothi) ingcolile; futhi ngenxa yokuthi uwoyela obuyayo we-breaker ngokuvamile awudluli endaweni epholile, kodwa ubuyela ngokuqondile ethangini likawoyela ngesihlungi sikawoyela, ngakho-ke umjikelezo kawoyela ojikelezayo ungase Ukushisa kwamafutha esekethe kawoyela osebenzayo kuphezulu kakhulu noma kuphakeme kakhulu, okuthinta kakhulu impilo yesevisi yezingxenye ze-hydraulic (ikakhulukazi izimpawu).
Ukuxazulula inkinga
Indlela ephumelela kakhulu yokuvimbela ukwehluleka okungenhla ukuthuthukisa i-hydraulic circuit. Enye iwukwengeza i-valve yokulayisha ngokweqile ku-valve eyinhloko ehlehlayo (uhlobo olufanayo lwe-valve yokulayisha ngokweqile njenge-boom noma i-valve yokusebenza yebhakede ingasetshenziswa), futhi ukucindezela kwayo okusethiwe kufanele kube ku-2~3MPa okukhulu kunaleyo ye-valve yokusiza, engakwazi ngokuphumelelayo Yehlisa umthelela wesistimu, futhi ngesikhathi esifanayo uqinisekise ukuthi ukucindezela kwesistimu ngeke kube phezulu kakhulu lapho i-valve yokusiza yonakaliswa; okwesibili ukuxhuma umugqa wokubuyisela uwoyela wesifunda sawoyela osebenzayo ku-cooler ukuze uqinisekise ukuthi uwoyela osebenzayo upholile ngesikhathi; okwesithathu yilapho ukugeleza kwepompo eyinhloko kudlula inani eliphakeme le-breaker Lapho izinga lokugeleza liyizikhathi ze-2, faka i-valve ye-diverter ngaphambi kwe-valve eyinhloko yokubuyisela emuva ukuze unciphise umthwalo we-valve yokusiza futhi uvimbele ukushisa okubangelwa inani elikhulu. kawoyela odlula ku-valve yokusiza. Ukuzijwayeza kufakazele ukuthi i-excavator ye-EX300 ethuthukisiwe (umshini omdala) efakwe i-KRB140 hydraulic breaker izuze imiphumela emihle yokusebenza.
Isizathu sephutha nokulungiswa
Ayisebenzi
1. Umfutho wenitrogen ekhanda elingemuva uphezulu kakhulu. ------ Lungisa ingcindezi evamile.
2. Izinga lokushisa likawoyela liphansi kakhulu. Ikakhulukazi ebusika obusenyakatho. ------- Khulisa ukulungiselelwa kokushisisa.
3. Ivalvu yokumisa ayivulwa. ------Vula ivalvu yokumisa.
4. Uwoyela we-hydraulic onganele. --------Engeza uwoyela we-hydraulic.
5. Umfutho wepayipi uphansi kakhulu ------- lungisa ukucindezela
6. Iphutha lokuxhumeka kwepayipi ------- ukuxhumana okulungile
7. Kunenkinga ngepayipi lokulawula ------ hlola ipayipi lokulawula.
8. Ivalvu yokuhlehla ibhajwe ------- iyagaya
9. I-Piston ibambekile------igaya
10. Ishizolo nephinikhodi kubanjiwe
11. Umfutho wenitrogen uphezulu kakhulu------lungisa inani elijwayelekile
Umthelela uphansi kakhulu
1. Ingcindezi yokusebenza iphansi kakhulu. Ukugeleza okunganele ------ lungisa ukucindezela
2. Umfutho we-nitrogen wekhanda elingemuva uphansi kakhulu-------lungisa umfutho we-nitrogen
3. Ingcindezi ephezulu ye-nitrogen enganele ------ engeza ukucindezela okujwayelekile
4. Ivalve ehlehlayo noma ipiston ilukhuni noma igebe likhulu kakhulu ------ liyagaya noma lishintshwa
5. Ukubuyiswa kukawoyela okubi ------ hlola ipayipi
Inombolo enganele yamahithi
1. Ukucindezela kwe-nitrogen ekhanda elingemuva kuphezulu kakhulu------lungisa inani elijwayelekile
2. I-valve ehlehlisayo noma i-piston brushing-------ukugaya
3. Ukubuyiswa kukawoyela okubi ------ hlola ipayipi

3. Lesi simo sizokwenzeka futhi lapho ukusebenza kwepompo ye-hydraulic kuphansi ----- lungisa iphampu yamafutha
4. Ishizolo alijwayelekile-----thatha indawo yeshizolo elijwayelekile
Ipayipi phezu kokudlidliza
1. Ingcindezi ephezulu ye-nitrogen iphansi kakhulu ------ engeza ezingeni
2. I-diaphragm yonakalisiwe------faka esikhundleni
3. Ipayipi aliboshiwe kahle------liphinde lalungiswa
4. Ukuvuza kukawoyela------buyisela uphawu lwamafutha olufanele
5. Ukuvuza komoya------buyisela uphawu lomoya
